A student was asked to determine the density of magnesium metal by the volume of displacement method. The student determined the density of magnesium as 1.89 g/mL. The accepted value for the density of magnesium is 1.74 g/mL. Calculate the percent error associated with the student's reported density.

The percent error is calculated using the formula: $\text{Percent Error} = \left| \frac{\text{Experimental Value} - \text{Accepted Value}}{\text{Accepted Value}} \right| \times 100\%$. Substituting the given values: $\left| \frac{1.89 - 1.74}{1.74} \right| \times 100\% = 8.6\%$.
